1. A rotorcraft, comprising:
- a body;
a power train coupled to the body and comprising a power source and a drive shaft coupled to the power source;
a hub coupled to the drive shaft;
a rotor blade;
a grip coupling the rotor blade to the hub; and
a position determination system disposed between the rotor blade and the body, the position determination system configured to measure a flapping of the rotor blade, the flapping of the rotor blade representing a vertical displacement of the rotor blade during operation, the position determination system comprising;
at least one magnet;
a plurality of magnet sensors proximate to the at least one magnet;
wherein the grip is positioned around a portion of the hub;
the grip has a closed end and an open end; and
the position determination system is disposed between the closed end of the grip and the at least part of the hub.
